[PATCH 1/3] wifi: ath12k: Refactor Rxdma buffer replinish argument

Currently, the Rxdma buffer replenish procedure implicitly retrieves the
number of free entries when the caller passes req_entries as zero. This is
helpful to replenishing the Rxdma ring when the caller is unaware of the
number of entries to replenish. After the Rxdma ring is initialized, we
can pass req_entries as zero to replenish all the free entry in the Rxdma
ring. This change helps to align the argument req_entries to the used list
entries for better code readability.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1
